Two charged particles are attracted to each other with a force of 7.6 newtons. what will happen if the distance between them shrinks to one third of what it started at?

The complete equation is as follows:

Force between two charge particles = k * Q1 * Q2 / r^2,

where k is constant, Q1 is charge on 1 particle, Q2 is charge on the other particle and r is the distance between the particles.

From the equation, if the distance between them shrinks to one third of what it started at, then the force will be 1/(1/3)^2 = 9 times larger.

It will become 7.6*9 = 68.4 Newtons.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
